Ryan and Gore get an A if they pull that off. If they get Suarez and either Kelly or Gallen, I'd give that an A- too.
Any scenario where they trade major piece(s) to get a closer like Clase, gets a C or D for me. I'd rather commit the big resources to a starter and go bargain shopping for BP help, then the other way around.
I hope they come away with Sandy Alcantara, Suarez, and a decent reliever like Garrett Whitlock. That would get an A+ for me. Addresses every need and they can possibly pull it off without giving up Owen.
